This part is actually called the fresh air door vent and if you are putting vacuum on it and the door is opening, then you have a problem somewhere else. Probably a vacuum hose loose or a defective vacuum select switch in the heater control.

We have a picture of the valve listed here: http://willcoxcorvette.com/repairand...lp.php?hID=172
And we also have the vacuum route chart which operates the valve listed here in our help section. http://willcoxcorvette.com/repairand...lp.php?hID=216
Both of these pictures can be found in the 76 AIM on Cd located here:

Thank you. The majority of the interior is apart, I figured since it was apart I should check the 2 vacuum valves. How do I check them? The other one is located along the firewall. I purchased the car with the majority of the interior disassembled and of course nothing was labeled.
